This invention l'elates to tie rod fastenings and it belongs to that classv of contrivances 'desi ned to secure the ends of rods against disp acement when subjecte'd to repeated v strains, blows or jolts. VVhile this invention may be employed as a fastening means for rodsdevoted to any kind of mechanicall comprisingparts 'of special` forlnation and disposition including a rod having a tapering end, whereby it is believed a fastening particularly strong,- easily made and long lasting is the result. Furthermore, in the 2 assembly of the parts certain members may be suitably expanded by heat and upon cooling they Will contract and cause frictional forces to be set up and thus additionallyn bind the parts together.

In the aceompa-nying drawings the special construction and arrangement of the parts are illustrated, and Fig. 1 represents the front portion of the top of a power haInmer withthis invention applied thereto. Fig. 2 is a view of the left hand end, and Fig. 3 is a view of the right hand end of a rod bearing this invention, the scale of drawingv being increased to enable the details of the construction to be more readily seen. Fig. 4 is a side view of a rod With this invention applied and shown partly in section. This view is taken on the Vertical line 4-4 of Fig. 2. Fig. 5 is a view of the tapering end of the rod With this invention applied thereto and shown in horizontal section on the line 5-5 of Fig. 2. Fig. 6 is a cross section through the rod taken along the line 6-6 i of Fig. 4 and shows a rear view of certain elements carried by the rod.

flanges 2 connected by the tie rods in anyv continual jarring movements' Throughout the description and drawings I claiInIis:

number such as the rod 3. The rod passes through the cylindrical hollow supports 4 and 5 with which the frame of the hammer is provided. The rod 3, as best shown in Fig.

4, has a'tapering end 6 and a sleeve 7 fitted' thereon, whichcannot be displaced towards the right hand side. The other end 8 of the rod is also oftapering form and is of reduced diameter.`

minations of the rod. c'

Surrounding the taperingand reduced end 8 are two members 9 andl 10 constituting When assembled a Sleeve which'interiorly fits. the reduced'tapering end 8 of the' rod 3 and the annular shoulder 8 fo'rmed at the junction of the tapering end 8 with the body 'of the rod. It will be observed in Fg. V5 lthat The larger end of the taper:w

ing p'ol-tons of the rod ends are at vthe terthe part'lO has a tangental groove 11.

Fittingthe cylindrical'exterior' of the com! posite sleeve is an external Sleeve 12 having on one slde a passage 13 which lnayl be brought to register Wlth the groove 11 ln the Vpart 10 of the internal sleeve.- Thepassage..` 13 and the groove 11 receive in binding rola-'lv tion a plug or Wedge 14, and it is'wthin the purview' of this invention to provide a' channel or bore 15 substantially parallel with the aXis of the rod 3, and through which there.

may be drven a plug or cotter pin, shown in Fig. 6 and d'esignated 15a, to fasten 'the wedge'14 in its place. i 1

The operation of his invention is believed to be readily discernible from the drawings and the foregoingr explanation. If the Inembers 9 and 10 of thecomposite or inner Sleeve be asselnbled on the reduced tapering end 8 of the rod, the external sleevev 12 may "be slipped thereon and the passage 13 Vbrought.,

to register With the groove 11 as stated'. If the parts are slightly'expanded by heat, the wedge Whendrivennin is held against any ordinary displacing efi`eot,ybut, if sol desired, a pin maybe passed through the boresl.
